His path to becoming an informant for the FBI is completely unique. It began in July of 2015 with a trip to the local library with his son. He saw what he considered an anti-Israel poster, which featured a Palestinian flag and described the situation in Israel as apartheid. He tore it down. “They have the right to put that up, and I have the right to take that down, in my opinion, so I did,” Day said of the incident. Then he passed along a photo of the poster to a friend who eventually posted about it on Facebook. The post went viral. Day was soon invited to a cookout attended by a number of members of a militia group in Kansas. Somewhere along the line the story got mixed up, and people in the militia believed that Day had found an ISIS recruiting poster. That wasn’t the case at all. But the FBI, which was looking into rumors of the ISIS poster, interviewed Day and ended up being interested in him because of his connection to the militia. It wasn’t long before Day was working on the bureau’s behalf, giving the federal government an inside look at the larger militia group.
